analyses are used. Of course a satisfactory classification would re- 

 quire many more analyses. Nevertheless these figures may be assumed 

 to give a tolerably fair idea of the relative composition of the fisk, or at 

 least, an approximation that may serve until more complete data are 

 obtained. Accordingly the order of the kinds in each of the four fol- 

 lowing groups must be regarded as by no means fixed, since further 

 analyses would very likely give averages varying more or less from 

 the results here tabulated, 



CLASSIFICATION OF SPECIMENS OF FISH BY AMOUNTS OF FLESH 

 (CHIEFLY MUSCULAR TISSUE) IN THE BODY, OR, IN OTHER WORDS, 

 BY THE RATIO OF THE WEIGHT OF THE FLESH TO THE SUM OF 

 WEIGHTS OF THE OTHER TISSUES.
